Precisely, set concrete with no water around does not conduct at all.

It's very good. Which is why people get shock in swimming pools and baths.

Negative, if one looks at an AM radio station the tower is used as the antenna. Note a big ceramic insulator between the tower and the foundation. the is a spark gap on the insulator for lighting. If the transmitter is active then a non conductive ladder to climb the tower. That is why maintenance is performed at night because they are off the air.

loor of your house while touching something live. This was suggested by so meone recently as being a danger. I just measured some concrete to make su re I wasn't being ignorant, and it was off the scale (>20MOhms)
, which is pretty damp.
Welcome to the idiot bin.

I like that link.
Page 5 has a table with ground electrode depths ranging between 3 and
1000 meters.Yes, meters. I'll assume they mean metres, which is well over half a mile... maybe they do mean a pile of 1000 testers?
Hmm... I wonder what they do mean?
Page 6 says "Just watch your units" :)
